PROSPECTUS SUPPLEMENT

TO THE SHORT FORM BASE SHELF PROSPECTUS DATED NOVEMBER 5, 2018

Up to US$100,000,000

Common Shares

This Prospectus Supplement, together with the accompanying Prospectus, qualifies the distribution (the “Offering”) of common shares (the “Common Shares” and each Common Share being qualified hereunder, an “Offered Share”) of First Majestic Silver Corp. (“First Majestic” or the “Company”) having an aggregate offering price of up to US$100,000,000. First Majestic has entered into an equity distribution agreement dated June 9, 2020 (the “Equity Distribution Agreement”) with BMO Capital Markets Corp. (“BMO”) and TD Securities (USA) LLC (“TD” and together with BMO, the “Agents”) pursuant to which First Majestic may distribute Offered Shares from time to time through the Agents, as agents or as principals for the distribution of the Offered Shares, in accordance with the terms of the Equity Distribution Agreement. See “Plan of Distribution”.

The outstanding Common Shares are listed for trading on the Toronto Stock Exchange (the “TSX”) under the symbol “FR” and on the New York Stock Exchange (the “NYSE”) under the symbol “AG”. On June 8, 2020, the last trading day on the TSX before the date of this Prospectus Supplement, the closing trading price of the Common Shares on the TSX was C$13.25 per Common Share. On June 8, 2020, the last trading day on the NYSE before the date of this Prospectus Supplement, the closing trading price of the Common Shares on the NYSE was US$9.92 per Common Share. The TSX has conditionally approved the listing of the Offered Shares offered hereunder, subject to the Company fulfilling all of the listing requirements of the TSX. In addition, the NYSE has approved the listing of the Offered Shares offered hereunder.

First Majestic is permitted, under a multi-jurisdictional disclosure system adopted by the securities regulatory authorities in Canada and the United States, to prepare this Prospectus Supplement in accordance with the disclosure requirements of Canada. Prospective investors in the United States should be aware that such requirements are different from those of the United States. The financial statements incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board and thus may not be comparable to financial statements of United States companies.

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that the Company is governed by the laws of British Columbia, Canada, that some or all of its officers and directors are residents of a foreign country, that some or all of the experts named in this Prospectus Supplement and the accompanying Prospectus are, and the experts and Agents named herein and in the Prospectus may be, residents of a foreign country, and a substantial portion of the assets of the Company and said persons may be located outside of the United States.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION (THE “SEC”) NOR ANY STATE OR CANADIAN SECURITIES COMMISSION OR REGULATORY AUTHORITY NOR HAS THE SEC OR ANY STATE OR CANADIAN SECURITIES COMMISSION OR REGULATORY AUTHORITY PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS SUPPLEMENT OR THE ACCOMPANYING PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

Prospective investors should be aware that the acquisition, holding or disposition of the Common Shares may have tax consequences in Canada and the United States. Such consequences for investors who are resident in, or citizens of, the United States may not be described fully herein. Prospective investors should read the tax discussion contained in this Prospectus Supplement under the heading “Certain U.S. Federal Income Tax Considerations” and should consult their own tax advisor with respect to their own particular circumstances.

Sales of Offered Shares, if any, under this Prospectus Supplement and the accompanying Prospectus are anticipated to be made in transactions that are deemed to be “at-the-market distributions” as defined in National Instrument 44-102 – Shelf Distributions (“NI 44-102”), including sales made directly on the NYSE or any other recognized marketplace upon which the Common Shares are listed or quoted or where the Common Shares are traded in the United States. No Offered Shares will be offered or sold in Canada on the TSX or any other trading market in Canada. If expressly authorized by the Company, the Agents may also sell Offered Shares in privately negotiated transactions in the United States. The sales, if any, of Offered Shares made under the Equity Distribution Agreement will be made by means of ordinary brokers’ transactions on the NYSE at market prices, or as otherwise agreed upon by the Company and the Agents. As a result, prices may vary as between purchasers and during the period of distribution. There is no minimum amount of funds that must be raised under the Offering. As a result, the Offering could be terminated after only raising a small portion of the offering amount set out above, or none at all. See “Plan of Distribution”.

In connection with the Offering, the Company may be considered to be a “connected issuer” within the meaning of National Instrument 33-105 – Underwriting Conflicts (“NI 33-105”) to BMO. An affiliate of BMO is a lender to the Company pursuant to the Revolving Facility (as defined herein). See “Plan of Distribution”.

The Company will pay each Agent a commission of up to 2.0% of the gross sales price per Offered Share sold through such Agent as the Company’s agent under the Equity Distribution Agreement.

Investing in the Offered Shares is subject to certain risks that should be considered carefully by prospective purchasers. Please see “Risk Factors” in the Prospectus Supplement and the accompanying Prospectus and the risk factors in the Company’s documents which are incorporated by reference herein for a description of risks involved in an investment in Offered Shares.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus Supplement and the accompanying Prospectus, and the documents incorporated by reference herein and therein, contain “forward-looking information” within the meaning of applicable Canadian securities legislation and “forward-looking statements” within the meaning of applicable U.S. securities legislation (collectively, “forward-looking statements”). These statements relate to future events or the Company’s future performance, business prospects or opportunities that are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management made in light of management’s experience and perception of historical trends, current conditions and expected future developments. Forward-looking statements include, but are not limited to statements with respect to:

S-5

All statements other than statements of historical fact may be forward-looking statements. Statements concerning Proven and Probable Mineral Reserves and Mineral Resource estimates may also be deemed to constitute forward-looking statements to the extent that they involve estimates of the mineralization that will be encountered as and if the property is developed, and in the case of Measured and Indicated Mineral Resources or Proven and Probable Mineral Reserves, such statements reflect the conclusion based on certain assumptions that

S-6

the mineral deposit can be economically exploited. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as “seek”, “anticipate”, “plan”, “continue”, “estimate”, “expect”, “may”, “will”, “project”, “predict”, “forecast”, “potential”, “targeting”, “intend”, “could”, “might”, “should”, “believe” and similar expressions) are not statements of historical fact and may be “forward-looking statements”.

Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements. These forward-looking statements involve risks and uncertainties relating to, among other things, global economic conditions, including public health threats, changes in commodity prices and, particularly, silver and gold prices, changes in exchange rates, access to skilled mining development and mill production personnel, labour relations, costs of labour, relations with local communities and aboriginal groups, results of exploration and development activities, accuracy of resource estimates, uninsured risks, defects in title, availability and costs of materials and equipment, inability to meet future financing needs on acceptable terms, availability of strategic alternatives, changes in national or local governments, risks associated with the COVID-19 pandemic, changes in applicable legislation or application thereof, timeliness of government approvals, results of litigation, negotiations and regulatory proceedings, actual performance of facilities, equipment, and processes relative to specifications and expectations and unanticipated environmental impacts on operations. Additional factors that could cause actual results to differ materially include, but are not limited to, the risk factors described under the heading “Risk Factors” in the Annual Information Form.

The Company believes that the expectations reflected in those forward-looking statements are reasonable, but no assurance can be given that these expectations will prove to be correct and such forward-looking statements included in this Prospectus Supplement or the accompanying Prospectus, including the documents incorporated by reference herein and therein, should not be unduly relied upon. These statements speak only as of the date of this Prospectus Supplement or as of the date specified in the documents incorporated by reference in this Prospectus Supplement, as the case may be. The Company does not intend, and does not assume any obligation, to update these forward-looking statements, except as required by applicable laws. Actual results may differ materially from those expressed or implied by such forward-looking statements.

CAUTIONARY NOTE TO UNITED STATES INVESTORS REGARDING

PRESENTATION OF MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES

This Prospectus Supplement and the accompanying Prospectus, including the documents incorporated by reference herein and therein, have been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. All mining terms used herein but not otherwise defined have the meanings set forth in National Instrument 43-101—Standards of Disclosure for Mineral Projects (“NI 43-101”). The definitions of Proven and Probable Mineral Reserves (“Mineral Reserves” or “Reserves”) used in NI 43-101 differ from the definitions in the SEC Industry Guide 7. Under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three year history average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority.

In addition, the terms “Mineral Resource”, “Measured Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. “Inferred Mineral Resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian securities laws, estimates of Inferred Mineral Resources may not form the basis of

S-7

feasibility or prefeasibility studies, except in certain specific cases. Additionally, disclosure of “contained ounces” in a resource is permitted disclosure under Canadian securities laws, however the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measurements.

Accordingly, information contained in this Prospectus Supplement and the accompanying Prospectus and the documents incorporated by reference herein and therein containing descriptions of the Company’s mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of United States federal securities laws and the rules and regulations thereunder.

See “Glossary of Certain Technical Terms” in the Annual Information Form, which is incorporated by reference herein, for a description of certain of the mining terms used in this Prospectus Supplement, the accompanying Prospectus and the documents incorporated by reference herein and therein.

RISK FACTORS

Before deciding to invest in the Offered Shares, prospective purchasers of the Offered Shares should consider carefully the risk factors and the other information contained in this Prospectus Supplement and the accompanying Prospectus and the documents incorporated by reference herein and therein before purchasing the Offered Shares. An investment in the Offered Shares is speculative and involves a high degree of risk. Information regarding the risks affecting the Company and its business is provided in the documents incorporated by reference in this Prospectus Supplement and the accompanying Prospectus, including in the Annual Information Form under the heading “General Development of the Business—Risk Factors”. Additional risks and uncertainties not known to the Company or that management currently deems immaterial may also impair the Company’s business, financial condition, results of operations or prospects. See “Documents Incorporated by Reference”.

Challenges to Advance Pricing Agreement

As more particularly set out in the Annual Information Form under “Risk Factors—Challenges to the Advance Pricing Agreement”, the Mexican tax authority, the Servicio de Administracion Tributaria (the “SAT”) initiated a proceeding in 2015 seeking to nullify the Advance Pricing Agreement (the “APA”) which it had previously issued to the Company’s subsidiary, Primero Empresa Minera, S.A. de C.V. (“PEM”) with respect to the San Dimas mine in 2012. The APA had confirmed PEM’s basis for paying taxes on the price PEM realized for silver sales pursuant to an internal stream agreement (the “Internal Stream”) with a Barbados affiliate between 2010 and 2014. If the SAT’s nullification challenge is successful it would have a material adverse effect on the Company’s business, financial condition and results of operations.

Since the SAT initiated nullification proceedings, the SAT has issued observation letters to PEM stating that PEM should pay taxes on the market price of silver sold under the Internal Stream and began issuing reassessments of taxation years 2010 to 2012. The Company has attempted to seek to resolve its differences with the SAT using both local administrative and legal procedures, including a constitutional challenge (called an amparo) before a District Court, and a complaint before Mexico’s Federal Taxpayer Defense Attorney’s Office (known as PRODECON), which proceedings have yet to be resolved. The Company has also sought to resolve these disputes pursuant to mutual agreement procedures contained in three separate double taxation treaties to which Mexico is party with Canada, Barbados and Luxembourg. The SAT has repeatedly and unilaterally rejected requests for dispute resolution pursuant to these mutual agreement procedures and has taken actions which the Company considers to be contrary to law to secure amounts it claims are owed pursuant to its reassessments of PEM issued in violation of the terms of the APA. These notifications impose certain restrictions on PEM’s ability to deal with its assets until this matter is resolved.

On May 13, 2020, the Company announced that it has taken steps to serve the Government of México with a Notice of Intent to Submit a Claim (“Notice”) under the provisions of Chapter 11 of the North American Free Trade Agreement (“NAFTA”) with respect to these matters. The service of the Notice by the Company on the Government of México initiated a 90-day process for the Government of México to enter into good faith and amicable negotiations with the Company to resolve the current dispute between the Company and the Government of México, however, there is no certainty that the Government of Mexico will abide by its obligations to enter into such negotiations or that such negotiations, if commenced, will result in a resolution in favour of the Company. The Company intends to continue to challenge the actions of the SAT in Mexican courts as well as through the NAFTA process, however due to the ongoing COVID-19 novel coronavirus (“COVID-19”) crisis, the Mexican courts are currently unavailable for further hearings on these matters.

Whether or not the SAT is successful in retroactively nullifying the APA, the SAT may seek to audit and reassess PEM in respect of its sales of silver for 2010 through 2014. The Company is unable to provide any certainty as to the outcome or timing of such challenge. While the Company may have rights of appeal in connection with any reassessments, if the legal proceeding is finally concluded in favor of the SAT, the amount

S-12

of additional taxes that the SAT could charge PEM for the tax years 2010 through 2014 would likely have a material adverse effect on the Company’s results of operations, financial condition and cash flows. In addition, whether or not SAT is successful in any proceedings and whether or not SAT has any legal basis to do so, the SAT may take further measures to restrict or seize PEM’s assets in Mexico, which could also have a material adverse effect on the Company.

Public Health Crises

Global financial conditions and the global economy in general have, at various times in the past and may in the future, experience extreme volatility in response to economic shocks or other events, such as the ongoing situation concerning COVID-19. Many industries, including the mining industry, are impacted by volatile market conditions in response to the widespread outbreak of epidemics, pandemics or other health crises. Such public health crises and the responses of governments and private actors can result in disruptions and volatility in economies, financial markets and global supply chains as well as declining trade and market sentiment and reduced mobility of people, all of which could impact commodity prices, interest rates, credit ratings, credit risk and inflation.

The Company’s business could be materially adversely affected by the effects of the COVID-19 outbreak. As at the date of this Prospectus Supplement, the global reactions to the spread of COVID-19 have led to, among other things, significant restrictions in many jurisdictions on travel and gatherings of individuals, quarantines, temporary business closures and a general reduction in consumer activity. While these effects are expected to be temporary, the duration of the disruptions to business internationally and the related financial impact cannot be estimated with any degree of certainty at this time. In addition, the increasing number of individuals infected with COVID-19 could result in a widespread global health crisis that could adversely affect global economies and financial markets, resulting in a protracted economic downturn that could have an adverse effect on the demand for precious metals and the Company’s future prospects.

In particular, the continued spread of COVID-19 globally could materially and adversely impact the Company’s business, including without limitation, employee health, workforce availability and productivity, limitations on travel, supply chain disruptions, increased insurance premiums, the availability of industry experts and personnel, restrictions on the Company’s exploration and drilling programs and/or the timing to process drill and other metallurgical testing and the slowdown or temporary suspension of operations at some or all of the Company’s properties, resulting in reduced production volumes. Although the Company has the capacity to continue certain administrative functions remotely, many other functions, including mining operations, cannot be conducted remotely.

On March 24, 2020, the Mexican federal government implemented a decree imposing certain preventive measures aimed at mitigating the impact of COVID-19. The decree temporarily suspended certain activities relating to physical gatherings and the transit or movement of individuals and was subsequently amended to restrict access and require the closure of the Company’s mines from April 3, 2020. On May 13, 2020, the Mexican government officially confirmed that mining was deemed essential and operations were permitted to restart on May 18, 2020. As a result, the Company initiated restart procedures at San Dimas, Santa Elena and La Encantada, however, there can be no guarantee that the decree will not be amended in the future to impose more severe measures or restrictions or that state governments in those jurisdictions in which the Company’s facilities are located will not pass similar decrees reducing or preventing access to the Company’s facilities, potentially causing disruption or closure of one or more of the Company’s mines.

As a result of the temporary closures of its facilities the Company has experienced loss of production at its facilities. As at early June the Company’s San Dimas and La Encantada facilities have returned to full production, however the Santa Elena facility is taking additional health safety precautions by creating a dedicated camp for its workers, therefore Santa Elena is currently operating at approximately 75% of full production and is not expected to return to full production until mid-June 2020. The full impact of such closures on the Company’s

S-13

production, revenue and net income has not yet been fully determined. There is no guarantee that the Company will not experience significant disruptions to or additional closures of some or all of its active mining operations in the future. Any such disruptions or closures could have a material adverse effect on the Company’s production, revenue, net income and business. In addition, parties with whom the Company does business or on whom the Company is reliant, including suppliers and refineries may also be adversely impacted by the COVID-19 crisis which may in turn cause further disruption to the Company’s business, including delays or halts in availability or delivery of consumables and delays or halts in refining of ore from the Company’s mines. Any long term closures or suspensions may also result in the loss of personnel or the workforce in general as employees seek employment elsewhere.

The impact of COVID-19 and government responses thereto may also continue to have a material impact on financial markets and could constrain the Company’s ability to obtain equity or debt financing in the future, which may have a material and adverse effect on its business, financial condition and results of operations.

No Assurance of Active or Liquid Market

No assurance can be given that an active or liquid trading market for the Common Shares will be sustained. If an active or liquid market for the Common Shares fails to be sustained, the prices at which such shares trade may be adversely affected. Whether or not the Common Shares will trade at lower prices depends on many factors, including the liquidity of the Common Shares, prevailing interest rates and the markets for similar securities, general economic conditions and the Company’s financial condition, historic financial performance and future prospects.

If the Offered Shares are traded after their initial issue, they may trade at a discount from their initial offering prices depending on the market and other factors including general economic conditions and the Company’s financial condition. There can be no assurance as to the liquidity of the trading market for the Common Shares.

Public Markets and Share Prices

The market price of the Offered Shares that become listed and posted for trading on the TSX, NYSE or any other stock exchange could be subject to significant fluctuations in response to variations in the Company’s financial results or other factors. In addition, fluctuations in the stock market may adversely affect the market price of the Offered Shares that become listed and posted for trading on a stock exchange regardless of the financial performance of the Company. Securities markets have also experienced significant price and volume fluctuations from time to time. In some instances, these fluctuations have been unrelated or disproportionate to the financial performance of issuers. Market fluctuations may adversely impact the market price of the Offered Shares that become listed and posted for trading on a stock exchange. There can be no assurance of the price at which the Offered Shares that become listed and posted for trading on a stock exchange will trade.

Additional Issuances and Dilution

The Company may issue and sell additional securities of the Company from time to time. The Company cannot predict the size of future issuances of securities of the Company or the effect, if any, that future issuances and sales of securities will have on the market price of any securities of the Company that are issued and outstanding from time to time. Sales or issuances of substantial amounts of securities of the Company, or the perception that such sales could occur, may adversely affect prevailing market prices for the securities of the Company that are issued and outstanding from time to time. With any additional sale or issuance of securities of the Company, holders will suffer dilution with respect to voting power and may experience dilution in the Company’s earnings per share. Moreover, this Prospectus Supplement and the accompanying Prospectus may create a perceived risk of dilution resulting in downward pressure on the price of the Company’s issued and outstanding Common Shares, which could contribute to progressive declines in the prices of such securities.

S-14

There is No Certainty Regarding the Net Proceeds to the Company

There is no certainty that US$100,000,000 will be raised under the Offering. The Agents have agreed to use their commercially reasonable efforts to sell the Offered Shares when and to the extent requested by the Company, but the Company is not required to request the sale of the maximum amount offered or any amount and, if the Company requests a sale, the Agents are not obligated to purchase any Offered Shares that are not sold. As a result of the Offering being made on a commercially reasonable efforts basis with no minimum, and only as requested by the Company, the Company may raise substantially less than the maximum total offering amount or nothing at all.

The Company has Broad Discretion in the Use of the Net Proceeds from the Offering and May Use Them in Ways Other than as Described Herein

Management of the Company will have broad discretion with respect to the application of net proceeds received by the Company under the Offering, if any, and may spend such proceeds in ways that do not improve the Company’s results of operations or enhance the value of the Common Shares or its other securities issued and outstanding from time to time. Any failure by management to apply these funds effectively could result in financial losses that could have a material adverse effect on the Company’s business or cause the price of the securities of the Company issued and outstanding from time to time to decline. Because of the number and variability of factors that will determine the Company’s use of such proceeds, if any, the Company’s ultimate use might vary substantially from its planned use. You may not agree with how the Company allocates or spend the proceeds from the Offering, if any.

RECENT DEVELOPMENTS

On April 3, 2020, the Company announced the temporary suspension of operations at San Dimas, Santa Elena and La Encantada in accordance with the Méxican Ministry of Health’s Federal Decree to mitigate the spread of COVID-19. On May 13, 2020, the Méxican government officially confirmed that mining was deemed essential and could restart on May 18, 2020. As a result, the Company initiated restart procedures at San Dimas, Santa Elena and La Encantada, while maintaining strict sanitary controls and supporting the local communities. Each of San Dimas and La Encantada have returned to full production rates while the Company expects Santa Elena to return to full production rates in mid-June. The Company has responded to the threat of COVID-19 through implementation of the following measures:

On April 14, 2020, the Company announced total production in the first quarter of 2020 reached 6.2 million silver equivalent ounces consisting of 3.2 million ounces of silver and 32,202 ounces of gold. The Company further confirmed that it had withdrawn its 2020 production and costs guidance as a result of the Méxican Ministry of Health Federal Decree to temporarily suspend all mining operations.

As discussed above under “Risk Factors—Challenges to Advance Pricing Agreement”, on May 13, 2020, the Company announced that it has taken steps to serve the Government of México with a Notice of Intent to Submit a Claim under the provisions of Chapter 11 of NAFTA with respect to the APA negotiated and finalized between the SAT and Primero, the Company’s Mexican subsidiary. The service of this Notice by the Company on the Government of México initiated a 90-day process for the Government of México to enter into good faith and amicable negotiations with the Company to resolve the current dispute between the Company and the Government of México. The Company has been in negotiations with the SAT with respect to the APA since its acquisition of Primero in May 2018, as more particularly set forth in the Annual Information Form. The SAT has repeatedly and unilaterally rejected requests for dispute resolution procedures, known as mutual agreement procedures contained in three separate double taxation treaties to which Mexico is party with Canada, Barbados and Luxembourg. The SAT has taken actions which the Company considers to be contrary to law to secure amounts it claims are owed pursuant to its reassessments of Primero issued in violation of the terms of the APA. These notifications impose certain restrictions on Primero’s ability to deal with its assets until this matter is resolved. The Company intends to continue to challenge the actions of the SAT in Mexican courts as well as through the NAFTA process, however due to the ongoing COVID-19 crisis, the Mexican courts are currently unavailable for further hearings on these matters and the outcome of such measures are uncertain.

USE OF PROCEEDS

The net proceeds from the Offering, if any, are not determinable in light of the nature of the distribution. The net proceeds of any given distribution of Offered Shares through the Agents in an “at-the-market distribution” will represent the gross proceeds after deducting the applicable compensation payable to the Agents under the Equity Distribution Agreement and the expenses of the distribution.

The principal business objectives that the Company expects to accomplish using the net proceeds from the Offering, if any, together with the Company’s current cash resources, are to develop and/or improve the Company’s existing mines and to add to the Company’s working capital.

PLAN OF DISTRIBUTION

The Company has entered into the Equity Distribution Agreement with the Agents, as sales agents, under which the Company may offer and sell Offered Shares having an aggregate offering price of up to US$100,000,000 from time to time. Sales of Offered Shares, if any, will be made in transactions that are deemed to be “at-the-market distributions” as defined in NI 44-102, including sales made directly on the NYSE or other trading markets for the Common Shares in the United States. No Offered Shares will be offered or sold in Canada on the TSX or on any other trading market in Canada. The sales, if any, of Offered Shares made under the Equity Distribution Agreement will be made by means of ordinary brokers’ transactions on the NYSE at market prices, or as otherwise agreed upon by the Company and the Agents. As a result, price may vary as between purchasers and during the period of distribution. The Agents will not engage in any transactions that stabilize the price of the Common Shares.

Under the terms of the Equity Distribution Agreement, the Company also may sell Common Shares to the Agents as principals for their own accounts at a price agreed upon at the time of sale. If the Company sells Common Shares to the Agents as principals, the Company will enter into a separate terms agreement with the Agents and the Company will describe this terms agreement in a separate prospectus supplement or pricing supplement.

The Company will designate the maximum amount of Offered Shares to be sold through an Agent on a daily basis or otherwise as the Company and such Agent agree and the minimum price per Offered Share at which such Offered Shares may be sold. Subject to the terms and conditions of the Equity Distribution Agreement, the applicable Agent will use its reasonable efforts to sell on the Company’s behalf all of the designated Offered Shares. The Company may instruct the applicable Agent not to sell any Offered Shares if the sales cannot be effected at or above the price designated by the Company in any such instruction. The Company or the applicable Agent may suspend the offering of the Offered Shares at any time and from time to time by notifying the other party.

Each of the Company and the Agents has the right, by giving written notice as specified in the Equity Distribution Agreement, to terminate the Equity Distribution Agreement in its sole discretion at any time.

The applicable Agent will provide to the Company written confirmation following the close of trading on the NYSE each day in which Offered Shares are sold under the Equity Distribution Agreement. Each confirmation will include the number of Offered Shares sold on that day, the gross sales proceeds and the net proceeds to the Company (after transaction fees, if any, but before other expenses). The Company will report at least quarterly the number of Offered Shares sold through the Agents under the Equity Distribution Agreement, the net proceeds to the Company (before expenses) and the commissions of the Agents in connection with the sales of the Offered Shares.

S-17

The Company will pay each Agent a commission of up to 2.0% of the gross sales price per Offered Share sold through such Agent as the Company’s agent under the Equity Distribution Agreement. The Company has agreed to reimburse the Agents for certain of their expenses.

Settlement for sales of Offered Shares will occur, unless the parties agree otherwise, on the second business day following the date on which any sales were made in return for payment of the net proceeds to the Company. There is no arrangement for funds to be received in an escrow, trust or similar arrangement. Sales of Offered Shares will be settled through the facilities of The Depository Trust Company or by such other means as the Company and the applicable Agent may agree upon.

The Agents are not registered as a dealer in any Canadian jurisdiction and, accordingly, are not permitted and will not, directly or indirectly, advertise or solicit offers to purchase any of the Offered Shares in Canada.

If the Company or any Agent has reason to believe that the Offered Shares are no longer “actively-traded securities” as defined under Rule 101(c)(l) of Regulation M under the Exchange Act, such party will promptly notify the others and sales of Offered Shares pursuant to the Equity Distribution Agreement or any terms agreement will be suspended until in the Company and Agents’ collective judgment Rule 101(c)(1) or another exemptive provision has been satisfied.

The offering of Offered Shares pursuant to the Equity Distribution Agreement will terminate upon the earlier of (i) the sale of all Offered Shares subject to the Equity Distribution Agreement; (ii) the termination of the Equity Distribution Agreement by the Company or by the Agents; or (iii) December 5, 2020.

In connection with the sale of the Offered Shares on the Company’s behalf, each Agent will be deemed to be an “underwriter” within the meaning of the U.S. Securities Act, and the compensation paid to the Agents may be deemed to be underwriting commissions or discounts. The Company has agreed to provide indemnification and contribution to the Agents against certain liabilities, including liabilities under the U.S. Securities Act. The Agents will not engage in any transactions that stabilize the price of the Common Shares. No underwriter or dealer involved in the distribution, no affiliate of such an underwriter or dealer and no person or company acting jointly or in concert with such an underwriter or dealer has over-allotted, or will over-allot, Common Shares in connection with the distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Common Shares.

The TSX has conditionally approved the listing of the Offered Shares offered hereunder, subject to the Company fulfilling all of the listing requirement of the TSX. In addition, the NYSE has approved the listing of the Offered Shares offered hereunder.

Selling Restrictions Outside of the United States

No action has been taken by the Company that would permit a public offering of the Offered Shares in any jurisdiction outside the United States where action for that purpose is required. The Offered Shares may not be offered or sold, directly or indirectly, nor may this Prospectus Supplement or any other offering material or advertisements in connection with the offer and sale of any such Offered Shares be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this Prospectus Supplement comes are advised to inform themselves about and to observe any restrictions relating to the Offering and the distribution of this Prospectus Supplement. This Prospectus Supplement does not constitute an offer to sell or a solicitation of an offer to buy any Offered Shares in any jurisdiction in which such an offer or a solicitation is unlawful.

S-18

Relationship between the Company and the Agents (Conflicts of Interest)

The Agents and their affiliates have performed investment banking, lending, commercial banking and advisory services for the Company from time to time for which they have received customary fees and expenses. From time to time, the Agents and/or their affiliates may in the future engage in investment banking and other commercial dealings in the ordinary course of business with the Company for which they would expect to receive customary fees and commissions.

In connection with the Offering, the Company may be considered to be a “connected issuer” (as defined in NI 33-105) to BMO under applicable Canadian securities legislation.

Bank of Montreal (which is a “related issuer”, as defined in NI 33-105, of the Agent) (the “Lender Affiliate”) is a member of a syndicate of lenders which extended to the Company a revolving term credit facility in the principal amount of US$75,000,000 (the “Revolving Facility”) pursuant to a credit agreement dated as of May 10, 2018. As of the date of this Prospectus Supplement an aggregate of approximately US$9,969,379 is drawn under the Revolving Facility. The Company is in compliance with the Revolving Facility and there have been no waivers granted since execution. The financial position of the Company has not materially changed since the indebtedness was incurred. The obligations under the Revolving Facility are secured. The Company reserves the right to use certain proceeds of the Offering to reduce the indebtedness under the Revolving Facility.

The decision to distribute the Offered Shares, including the determination of the terms of the Offering, was made through arm’s length negotiations between the Company and the Agents. The Lender Affiliate did not have any involvement in such decision or determination. As a consequence of the Offering, BMO will receive its commission and, to the extent any of the proceeds of the Offering are applied to reduce the indebtedness under the Revolving Facility, the Lender Affiliate will receive its proportionate share of the repaid indebtedness.

As a result, BMO or the Lender Affiliate may receive more than 5% of the net proceeds from the sale of the Offered Shares in the form of the repayment of such indebtedness. Accordingly, the Offering is being made pursuant to Rule 5121 of the Financial Industry Regulatory Authority, Inc. Pursuant to this rule, the appointment of a qualified independent underwriter is not necessary in connection with the Offering, because the conditions of Rule 5121(a)(1)(B) are satisfied. BMO and the Lender Affiliate may also make investment recommendations and/or publish or express independent research views in respect of the Company’s securities or financial instruments related to the Company’s securities and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a general summary of certain material U.S. federal income tax considerations applicable to a U.S. Holder (as defined below) arising from and relating to the acquisition, ownership, and disposition of Offered Shares acquired pursuant to the Offering.

This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a U.S. Holder arising from and

S-25

relating to the acquisition, ownership, and disposition of Offered Shares. In addition, this summary does not take into account the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such U.S. Holder, including, without limitation, specific tax consequences to a U.S. Holder under an applicable income tax treaty. Accordingly, this summary is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any U.S. Holder. This summary does not address the U.S. federal alternative minimum, U.S. federal net investment income, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences to U.S. Holders of the acquisition, ownership, and disposition of Offered Shares. In addition, except as specifically set forth below, this summary does not discuss applicable tax reporting requirements. Each prospective U.S. Holder should consult its own tax advisor regarding the U.S. federal income, U.S. federal alternative minimum, U.S. federal net investment income, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership, and disposition of Offered Shares.

No ruling from the Internal Revenue Service (the “IRS”) has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Offered Shares. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary are based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the conclusions described in this summary.

Scope of this Summary

Authorities

This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations (whether final, temporary, or proposed), published rulings of the IRS, published administrative positions of the IRS, the Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, signed September 26, 1980, as amended (the “Canada-U.S. Tax Convention”), and U.S. court decisions that are applicable, and, in each case, as in effect and available, as of the date of this document. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied retroactively. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation.

U.S. Holders

For purposes of this summary, the term “U.S. Holder” means a beneficial owner of Offered Shares acquired pursuant to the Offering that is for U.S. federal income tax purposes:

U.S. Holders Subject to Special U.S. Federal Income Tax Rules Not Addressed

This summary does not address the U.S. federal income tax considerations applicable to U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders that: (a) are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred

S-26

accounts; (b) are financial institutions, underwriters, insurance companies, real estate investment trusts, or regulated investment companies; (c) are broker-dealers, dealers, or traders in securities or currencies that elect to apply a mark-to-market accounting method; (d) have a “functional currency” other than the U.S. dollar; (e) own Offered Shares as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other integrated transaction; (f) acquire Offered Shares in connection with the exercise of employee stock options or otherwise as compensation for services; (g) hold Offered Shares other than as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes); (h) are subject to special tax accounting rules; or (i) own, have owned or will own (directly, indirectly, or by attribution) 10% or more of the total combined voting power or value of the outstanding shares of the Company. This summary also does not address the U.S. federal income tax considerations applicable to U.S. Holders who are: (a) U.S. expatriates or former long-term residents of the U.S.; (b) persons that have been, are, or will be a resident or deemed to be a resident in Canada for purposes of the Income Tax Act (Canada) (the “Tax Act”); (c) persons that use or hold, will use or hold, or that are or will be deemed to use or hold Offered Shares in connection with carrying on a business in Canada; (d) persons whose Offered Shares constitute “taxable Canadian property” under the Tax Act; or (e) persons that have a permanent establishment in Canada for the purposes of the Canada-U.S. Tax Convention. U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders described immediately above, should consult their own tax advisor regarding the U.S. federal income, U.S. federal alternative minimum, U.S. federal net investment income, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership and disposition of Offered Shares.

If an entity or arrangement that is classified as a partnership (or other “pass-through” entity) for U.S. federal income tax purposes holds Offered Shares, the U.S. federal income tax consequences to such entity and the partners (or other owners) of such entity generally will depend on the activities of the entity and the status of such partners (or owners). This summary does not address the tax consequences to any such partner (or owner). Partners (or other owners) of entities or arrangements that are classified as partnerships or as “pass-through” entities for U.S. federal income tax purposes should consult their own tax advisors regarding the U.S. federal income tax consequences arising from and relating to the acquisition, ownership, and disposition of Offered Shares.

Ownership and Disposition of Offered Shares

The following discussion is subject in its entirety to the rules described below under the heading “Passive Foreign Investment Company Rules”.

Taxation of Distributions

A U.S. Holder that receives a distribution, including a constructive distribution, with respect to an Offered Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any foreign income tax withheld from such distribution) to the extent of the current or accumulated “earnings and profits” of the Company, as computed for U.S. federal income tax purposes. To the extent that a distribution exceeds the current and accumulated “earnings and profits” of the Company, such distribution will be treated first as a tax-free return of capital to the extent of a U.S. Holder’s tax basis in the Offered Shares and thereafter as gain from the sale or exchange of such Offered Shares (see “Sale or Other Taxable Disposition of Offered Shares” below). However, the Company may not maintain the calculations of its earnings and profits in accordance with U.S. federal income tax principles, and each U.S. Holder may have to assume that any distribution by the Company with respect to the Offered Shares will constitute dividend income. Dividends received on Offered Shares by corporate U.S. Holders generally will not be eligible for the “dividends received deduction”. Subject to applicable limitations and provided the Company is eligible for the benefits of the Canada-U.S. Tax Convention or the Offered Shares are readily tradable on a United States securities market, dividends paid by the Company to non-corporate U.S. Holders, including individuals, generally will be eligible for the preferential tax rates applicable to long-term capital gains for dividends, provided certain holding period and other conditions are satisfied, including that the Company not be classified as a PFIC (as defined below) in

S-27

the tax year of distribution or in the preceding tax year. The dividend rules are complex, and each U.S. Holder should consult its own tax advisor regarding the application of such rules.

Sale or Other Taxable Disposition of Offered Shares

A U.S. Holder will generally recognize gain or loss on the sale or other taxable disposition of Offered Shares in an amount equal to the difference, if any, between (a) the amount of cash plus the fair market value of any property received and (b) such U.S. Holder’s tax basis in such Offered Shares sold or otherwise disposed of. Any such gain or loss generally will be capital gain or loss, which will be long-term capital gain or loss if, at the time of the sale or other disposition, such Offered Shares are held for more than one year.

Preferential tax rates apply to long-term capital gains of a U.S. Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gains of a U.S. Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code.

Passive Foreign Investment Company Rules

If the Company were to constitute a “passive foreign investment company” (“PFIC”) for any year during a U.S. Holder’s holding period, then certain potentially adverse rules would affect the U.S. federal income tax consequences to a U.S. Holder resulting from the acquisition, ownership and disposition of Offered Shares. The Company believes that it was not a PFIC for the prior tax year, and based on current business plans and financial expectations, the Company expects that it will not be a PFIC for the current tax year and expects that it will not be a PFIC for the foreseeable future. No opinion of legal counsel or ruling from the IRS concerning the status of the Company as a PFIC has been obtained or is currently planned to be requested. However, PFIC classification is fundamentally factual in nature, generally cannot be determined until the close of the tax year in question, and is determined annually. In addition, the analysis depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. Consequently, there can be no assurance that the Company has never been and will not become a PFIC for any tax year during which U.S. Holders hold Offered Shares.

In any year in which the Company is classified as a PFIC, a U.S. Holder will be required to file an annual report with the IRS containing such information as Treasury Regulations and/or other IRS guidance may require. In addition to penalties, a failure to satisfy such reporting requirements may result in an extension of the time period during which the IRS can assess a tax. U.S. Holders should consult their own tax advisors regarding the requirements of filing such information returns under these rules, including the requirement to file an IRS Form 8621 annually.

The Company generally will be a PFIC if, after the application of certain “look-through” rules with respect to subsidiaries in which the Company holds at least 25% of the value of such subsidiary, for a tax year, (a) 75% or more of the gross income of the Company for such tax year is passive income (the “income test”) or (b) 50% or more of the value of the Company’s assets either produce passive income or are held for the production of passive income (the “asset test”), based on the quarterly average of the fair market value of such assets. “Gross income” generally includes all sales revenues less the cost of goods sold, plus income from investments and from incidental or outside operations or sources, and “passive income” generally includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions. Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all of a foreign corporation’s commodities are stock in trade or inventory, depreciable property used in a trade or business or supplies regularly used or consumed in the ordinary course of its trade or business, and certain other requirements are satisfied.

If the Company were a PFIC in any tax year during which a U.S. Holder held Offered Shares, such holder generally would be subject to special rules with respect to “excess distributions” made by the Company on the

S-28

Offered Shares and with respect to gain from the disposition of Offered Shares. An “excess distribution” generally is defined as the excess of distributions with respect to the Offered Shares received by a U.S Holder in any tax year over 125% of the average annual distributions such U.S. Holder has received from the Company during the shorter of the three preceding tax years, or such U.S. Holder’s holding period for the Offered Shares. Generally, a U.S. Holder would be required to allocate any excess distribution or gain from the disposition of the Offered Shares ratably over its holding period for the Offered Shares. Such amounts allocated to the year of the disposition or excess distribution would be taxed as ordinary income, and amounts allocated to prior tax years would be taxed as ordinary income at the highest tax rate in effect for each such year and an interest charge at a rate applicable to underpayments of tax would apply.

While there are U.S. federal income tax elections that sometimes can be made to mitigate these adverse tax consequences (including the “QEF Election” under Section 1295 of the Code and the “Mark-to-Market Election” under Section 1296 of the Code), such elections are available in limited circumstances and must be made in a timely manner.

U.S. Holders should be aware that, for each tax year, if any, that the Company is a PFIC, the Company can provide no assurances that it will satisfy the record keeping requirements or make available to U.S. Holders the information such U.S. Holders require to make a QEF Election with respect to the Company or any subsidiary that also is classified as a PFIC.

Certain additional adverse rules may apply with respect to a U.S. Holder if the Company is a PFIC, regardless of whether the U.S. Holder makes a QEF Election. These rules include special rules that apply to the amount of foreign tax credit that a U.S. Holder may claim on a distribution from a PFIC. Subject to these special rules, foreign taxes paid with respect to any distribution in respect of stock in a PFIC are generally eligible for the foreign tax credit. U.S. Holders should consult their own tax advisors regarding the potential application of the PFIC rules to the ownership and disposition of Offered Shares, and the availability of certain U.S. tax elections under the PFIC rules.

Additional Considerations

Receipt of Foreign Currency

The amount of any distribution paid to a U.S. Holder in foreign currency, or on the sale, exchange or other taxable disposition of Offered Shares, generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into U.S. dollars at that time). A U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any U.S. Holder who converts or otherwise disposes of the foreign currency after the date of receipt may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be U.S. source income or loss for foreign tax credit purposes. Different rules apply to U.S. Holders who use the accrual method of tax accounting. Each U.S. Holder should consult its own U.S. tax advisor regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency.

Foreign Tax Credit

Subject to the PFIC rules discussed above, a U.S. Holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the Offered Shares generally will be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax. Generally, a credit will reduce a U.S. Holder’s U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder’s income that is subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during a year. The foreign tax credit rules are complex and involve the application of rules that

S-29

depend on a U.S. Holder’s particular circumstances. Accordingly, each U.S. Holder should consult its own U.S. tax advisor regarding the foreign tax credit rules.

Backup Withholding and Information Reporting

Under U.S. federal income tax law and Treasury Regulations, certain categories of U.S. Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, U.S. return disclosure obligations (and related penalties) are imposed on individuals who are U.S. Holders that hold certain specified foreign financial assets in excess of certain threshold amounts. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign entity. U. S. Holders may be subject to these reporting requirements unless their Offered Shares are held in an account at certain financial institutions. Penalties for failure to file certain of these information returns are substantial. U.S. Holders should consult their own tax advisors regarding the requirements of filing information returns, including the requirement to file an IRS Form 8938.

Payments made within the U.S. or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of, Offered Shares will generally be subject to information reporting and backup withholding tax, at the rate of 24%, if a U.S. Holder (a) fails to furnish such U.S. Holder’s correct U.S. taxpayer identification number (generally on Form W-9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such U.S. Holder has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. Holder that it is subject to backup withholding tax. However, certain exempt persons generally are excluded from these information reporting and backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the U.S. backup withholding tax rules generally will be allowed as a credit against a U.S. Holder’s U.S. federal income tax liability, if any, or will be refunded, if such U.S. Holder furnishes required information to the IRS in a timely manner.

The discussion of reporting requirements set forth above is not intended to constitute a complete description of all reporting requirements that may apply to a U.S. Holder. A failure to satisfy certain reporting requirements may result in an extension of the time period during which the IRS can assess a tax, and under certain circumstances, such an extension may apply to assessments of amounts unrelated to any unsatisfied reporting requirement. Each U.S. Holder should consult its own tax advisor regarding the information reporting and backup withholding rules.

THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL TAX CONSIDERATIONS APPLICABLE TO U.S. HOLDERS WITH RESPECT TO THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF OFFERED SHARES. U.S. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE TAX CONSIDERATIONS APPLICABLE TO THEM IN THEIR OWN PARTICULAR CIRCUMSTANCES.

B.C. and Seattle, WA, as to United States legal matters. As of the date hereof, the partners and associates of Bennett Jones LLP own, directly or indirectly, less than 1% of the Common Shares and the partners and associates of Dorsey & Whitney LLP own, directly or indirectly, less than 1% of the Common Shares. In addition, certain legal matters in connection with the Offering will be passed upon for the Agents by Blake, Cassels & Graydon LLP, Vancouver, B.C., as to Canadian legal matters, and Paul, Weiss, Rifkind, Wharton & Garrison LLP, New York, NY, as to United States legal matters.

ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

The Company is governed by the laws of British Columbia and its principal place of business is outside the United States. The majority of the directors and officers of the Company and the experts named under “Interests of Experts” in the Prospectus are resident outside of the United States and a substantial portion of the Company’s assets and the assets of such persons are located outside of the United States. Consequently, it may be difficult for United States investors to effect service of process within the United States on the Company, its directors or officers or such experts, or to realize in the United States on judgments of courts of the United States predicated on civil liabilities under the U.S. Securities Act. Investors should not assume that Canadian courts would enforce judgments of United States courts obtained in actions against the Company or such persons predicated on the civil liability provisions of the United States federal securities laws or the securities or “blue sky” laws of any state within the United States or would enforce, in original actions, liabilities against the Company or such persons predicated on the United States federal securities or any such state securities or “blue sky” laws. A final judgment for a liquidated sum in favour of a private litigant granted by a United States court and predicated solely upon civil liability under United States federal securities laws would, subject to certain exceptions identified in the law of individual provinces of Canada, likely be enforceable in Canada if the United States court in which the judgment was obtained had a basis for jurisdiction in the matter that would be recognized by the domestic Canadian court for the same purposes. There is a significant risk that a given Canadian court may not have jurisdiction or may decline jurisdiction over a claim based solely upon United States federal securities law on application of the conflict of laws principles of the province in Canada in which the claim is brought.

The Company filed with the SEC, concurrently with the Registration Statement, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Company appointed Puglisi & Associates, with an address at 850 Library Avenue, Suite 204, Newark, Delaware 19711, as its agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against or involving the Company in a United States court arising out of or related to or concerning the offering of the Offered Shares under the Registration Statement.

AUDITOR, TRANSFER AGENT AND REGISTRAR

The auditor of the Company is Deloitte LLP, Chartered Professional Accountants, of 939 Granville Street, Vancouver, British Columbia, V6Z 1L3. Deloitte LLP is independent with respect to the Company within the meaning of the U.S. Securities Act and the applicable rules and regulations thereunder adopted by the Securities and Exchange Commission (SEC) and the Public Company Accounting Oversight Board (United States) (PCAOB) and within the meaning of the rules of professional conduct of the Chartered Professional Accountants of British Columbia.

The transfer agent and registrar for the Common Shares is Computershare Investor Services Inc. at its principal office in Vancouver, British Columbia. Computershare, Inc. acts as co-transfer agent for the Common Shares in the United States and has its principal office in Canton, Massachusetts.

S-32

This short form prospectus is a base shelf prospectus. This short form base shelf prospectus has been filed under legislation in each of the provinces of Canada other than Québec (the “Qualifying Provinces”) that permits certain information about these securities to be determined after this prospectus has become final and that permits the omission from this prospectus of that information. The legislation requires the delivery to purchasers of a prospectus supplement containing the omitted information within a specified period of time after agreeing to purchase any of these securities.

No securities regulatory authority has expressed an opinion about these securities and it is an offence to claim otherwise. This short form base shelf prospectus constitutes a public offering of these securities only in those jurisdictions where they may be lawfully offered for sale therein and only by persons permitted to sell such securities. See “Plan of Distribution”.

Information has been incorporated by reference in this short form base shelf prospectus from documents filed with securities commissions or similar authorities in Canada. Copies of the documents incorporated herein by reference may be obtained on request without charge from the Secretary of the Company at its head office at 1800 - 925 West Georgia Street, Vancouver, British Columbia, V6C 3L2, telephone (604) 688-3033 and are also available electronically at www.sedar.com.

SHORT FORM BASE SHELF PROSPECTUS

US$300,000,000

Common Shares

Subscription Receipts

Units

Warrants

This short form base shelf prospectus (the “Prospectus”) relates to the offer and sale by First Majestic Silver Corp. (“First Majestic”, the “Company”, “we” or “us”) from time to time of common shares (the “Common Shares”), subscription receipts (the “Subscription Receipts”), warrants to purchase other Securities (as defined herein) (the “Warrants”) and units (the “Units”) comprised of one or more of any of the other securities or any combination of such securities (all of the foregoing, collectively, the “Securities”) or any combination thereof in one or more series or issuances up to an aggregate total offering price of US$300,000,000 (or the equivalent thereof in Canadian dollars or any other currencies) during the 25-month period that this Prospectus, including any amendments thereto, remains effective. The Securities may be offered separately or together, in amounts, at prices and on terms to be determined based on market conditions at the time of sale and set forth in an accompanying shelf prospectus supplement (each, a “Prospectus Supplement”). In addition, the Securities may be offered and issued in consideration for the acquisition of other businesses, assets or securities by the Company or one of its subsidiaries. The consideration for any such acquisition may consist of the Securities separately, a combination of Securities or any combination of, among other things, Securities, cash and assumption of liabilities.

First Majestic is permitted, under a multi-jurisdictional disclosure system adopted by the securities regulatory authorities in Canada and the United States, to prepare this Prospectus in accordance with the disclosure requirements of Canada. Prospective investors in the United States should be aware that such requirements are different from those of the United States. The financial statements incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board and thus may not be comparable to financial statements of United States companies.

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that the Company is governed by the laws of British Columbia, Canada, that some or all of its officers and directors are residents of a foreign country, that some or all of the experts named in this Prospectus are, and the underwriters, dealers or agents named in any Prospectus Supplement may be, residents of a foreign country, and a substantial portion of the assets of the Company and said persons may be located outside of the United States.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION (THE “SEC”) NOR ANY STATE OR CANADIAN SECURITIES COMMISSION OR REGULATORY AUTHORITY NOR HAS THE SEC OR ANY STATE OR CANADIAN SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

Prospective investors should be aware that the acquisition of the Securities may have tax consequences in Canada and the United States. Such consequences may not be described fully herein or in any applicable Prospectus Supplement. Prospective investors should read the tax discussion contained in this Prospectus under the heading “Certain Federal Income Tax Considerations” as well as the tax discussion, if any, contained in the applicable Prospectus Supplement with respect to a particular offering of Securities.

The specific terms of the Securities with respect to a particular offering will be set out in the applicable Prospectus Supplement, including, where applicable: (i) in the case of Common Shares, the number of Common Shares offered, the offering price, whether the Common Shares are being offered for cash, and any other terms specific to the Common Shares; (ii) in the case of Warrants, the number of Warrants being offered, the offering price, whether the Warrants are being offered for cash, the designation, number and terms of the other Securities purchasable upon exercise of the Warrants, and any procedures that will result in the adjustment of those numbers, the exercise price, the dates and periods of exercise and any other terms specific to the Warrants being offered; (iii) in the case of Subscription Receipts, the number of Subscription Receipts being offered, the offering price, whether the Subscription Receipts are being offered for cash, the terms, conditions and procedures for the conversion of the Subscription Receipts into other Securities, the designation, number and terms of such other Securities, and any other terms specific to the Subscription Receipts; and (iv) in the case of Units, the number of Units being offered, the offering price and the number and terms of the Securities comprising the Units. See “Plan of Distribution”. A Prospectus Supplement relating to a particular offering of Securities may include terms pertaining to the Securities being offered thereunder that are not within the terms and parameters described in this Prospectus. Where required by statute, regulation or policy, and where Securities are offered in currencies other than Canadian dollars, appropriate disclosure of foreign exchange rates applicable to such Securities will be included in the Prospectus Supplement describing such Securities.

All applicable shelf information permitted under applicable laws to be omitted from this Prospectus that has been omitted will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with this Prospectus, except in cases where an exemption from such delivery has been obtained. Each Prospectus Supplement will be incorporated by reference into this Prospectus for the purposes of securities legislation as of the date of the Prospectus Supplement and only for the purposes of the distribution of the Securities to which the Prospectus Supplement pertains. Prospective investors should read this Prospectus and any applicable Prospectus Supplement carefully before investing in any Securities issued pursuant to this Prospectus.

The Company may offer and sell Securities to, or through, underwriters, dealers or agents and may also offer and sell certain Securities directly to other purchasers or through agents pursuant to exemptions under applicable securities laws. See “Plan of Distribution”. The Prospectus Supplement relating to each issue of Securities offered pursuant to this Prospectus will set forth the names of any underwriters, dealers or agents involved in the offering and sale of such Securities and will set forth the terms of the offering of such Securities, the method of distribution of such Securities including, to the extent applicable, the proceeds to the Company, if any, and any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms of the plan of distribution.

No underwriter has been involved in the preparation of this Prospectus or performed any review of the contents of this Prospectus.

The Securities may be sold from time to time in one or more transactions at a fixed price or prices or at non-fixed prices. If offered on a non-fixed price basis, the Securities may be offered at market prices prevailing at the time of sale, at prices determined by reference to the prevailing price of a specified Security in a specified market or at prices to be negotiated with purchasers, in which case the compensation payable to an underwriter, dealer or agent in connection with any such sale will be decreased by the amount, if any, by which the aggregate price paid for Securities by the purchasers is less than the gross proceeds paid by the underwriter, dealer or agent to the Company. The price at which the Securities will be offered and sold may vary from purchaser to purchaser and during the period of distribution.

In connection with any offering of Securities, except as otherwise set out in a Prospectus Supplement relating to a particular offering of Securities, the underwriters, dealers or agents may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at a level above that which might otherwise prevail in the open market. Such transactions may be commenced, interrupted or discontinued at any time. However, no underwriter, dealer or agent involved in an “at-the-market distribution”, as defined in National Instrument 44-102 – Shelf Distributions (“NI 44-102”), no affiliate of such an underwriter, dealer or agent and no person or company acting jointly or in concert with such an underwriter, dealer or agent will over-allot Securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities. A purchaser who acquires Securities forming part of the underwriters’, dealers’ or agents’ over-allotment position acquires those Securities under this Prospectus and the Prospectus Supplement relating to the particular offering of Securities, regardless of whether the over-allotment position is ultimately filled through the exercise of the over-allotment option or secondary market purchases. See “Plan of Distribution”.

The outstanding Common Shares are listed and posted for trading on the Toronto Stock Exchange (the “TSX”) under the symbol “FR” and are listed on the New York Stock Exchange (the “NYSE”) under the symbol “AG”. On November 2, 2018, the last trading day prior to the date of this Prospectus, the closing price of the Common Shares on the TSX was C$7.77 and on the NYSE was US$5.92.

Unless otherwise specified in the applicable Prospectus Supplement, Subscription Receipts, Units and Warrants will not be listed on any securities exchange. Consequently, unless otherwise specified in the applicable Prospectus Supplement, there is no market through which the Subscription Receipts, Units and Warrants may be sold and purchasers may not be able to resell any such Securities purchased under this Prospectus. This may affect the pricing of the Subscription Receipts, Units and Warrants in the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation. See “Risk Factors”.

This Prospectus constitutes a public offering of these Securities only in those jurisdictions where they may be lawfully offered for sale and therein only by persons permitted to sell such Securities.

Investing in the Securities involves significant risks. Prospective purchasers of the Securities should carefully consider the risk factors described under the heading “Risk Factors” and elsewhere in this Prospectus, in documents incorporated by reference in this Prospectus and in the applicable Prospectus Supplement with respect to a particular offering of Securities.

All dollar amounts in this Prospectus are in United States dollars, unless otherwise indicated. See “Currency Presentation and Exchange Rate Information”.

The Company’s head office is located at 1800 - 925 West Georgia Street, Vancouver, British Columbia, V6C 3L2, and its registered office is located at 2600 - 1066 West Hastings Street, Vancouver, British Columbia, Canada V6E 3X1.

Prospective investors are advised that it may not be possible for investors to enforce judgements obtained in Canada against any person or company that is incorporated, continued or otherwise organized under the laws of a foreign jurisdiction or resides outside of Canada, even if the party has appointed an agent for service of process.

Readers should rely only on the information contained or incorporated by reference in this Prospectus and any applicable Prospectus Supplement. The Company has not authorized anyone to provide readers with different information. The Company is not making an offer to sell or seeking an offer to buy the Securities in any jurisdiction where the offer or sale is not permitted.

Market data and certain industry forecasts used in this Prospectus or any applicable Prospectus Supplement and the documents incorporated by reference herein or therein were obtained from market research, publicly available information and industry publications.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING INFORMATION

Certain statements contained in this Prospectus and the documents incorporated by reference herein constitute forward-looking information or forward-looking statements under applicable securities laws (collectively, “forward-looking statements”). These statements relate to future events or the Company’s future performance, business prospects or opportunities that are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management made in light of management’s experience and perception of historical trends, current conditions and expected future developments. Forward-looking statements include, but are not limited to statements with respect to:

6

All statements other than statements of historical fact may be forward-looking statements. Statements concerning Proven and Probable Mineral Reserves and Mineral Resource estimates may also be deemed to constitute forward-looking statements to the extent that they involve estimates of the mineralization that will be encountered as and if the property is developed, and in the case of Measured and Indicated Mineral Resources or Proven and Probable Mineral Reserves, such statements reflect the conclusion based on certain assumptions that the mineral deposit can be economically exploited. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as “seek”, “anticipate”, “plan”, “continue”, “estimate”, “expect”, “may”, “will”, “project”, “predict”, “forecast”, “potential”, “targeting”, “intend”, “could”, “might”, “should”, “believe” and similar expressions) are not statements of historical fact and may be “forward-looking statements”.

Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements. These forward-looking statements involve risks and uncertainties relating to, among other things, global economic conditions, changes in commodity prices and, particularly, silver and gold prices, changes in exchange rates, access to skilled mining development and mill production personnel, labour relations, costs of labour, relations with local communities and aboriginal groups, results of exploration and development activities, accuracy of resource estimates, uninsured risks, defects in title, availability and costs of materials and equipment, inability to meet future financing needs on acceptable terms, availability of strategic alternatives, changes in national or local governments, changes in applicable legislation or application thereof, timeliness of government approvals, results of litigation, actual performance of facilities, equipment, and processes relative to specifications and expectations and unanticipated environmental impacts on operations. Additional factors that could cause actual results to differ materially include, but are not limited to, the risk factors described under the heading “Risk Factors” in the Annual Information Form.

The Company believes that the expectations reflected in those forward-looking statements are reasonable, but no assurance can be given that these expectations will prove to be correct and such forward-looking statements included in, or incorporated by reference into, this Prospectus should not be unduly relied upon. These statements speak only as of the date of this Prospectus or as of the date specified in the documents incorporated by reference into this Prospectus, as the case may be. The Company does not intend, and does not assume any obligation, to update these forward-looking statements, except as required by applicable laws. Actual results may differ materially from those expressed or implied by such forward-looking statements.

CAUTIONARY NOTE TO UNITED STATES INVESTORS REGARDING

PRESENTATION OF MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES

This Prospectus, including the documents incorporated by reference herein, has been prepared in accordance with the requirements of the securities laws in effect in Canada which differ from the requirements of United States securities laws. All mining terms used herein but not otherwise defined have the meanings set forth in National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”). The definitions of Proven and Probable Reserves (“Mineral Reserves” or “Reserves”) used in NI 43-101 differ from the definitions in the SEC Industry Guide 7. Under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three year history average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority.

In addition, the terms “Mineral Resource”, “Measured Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. “Inferred Mineral Resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian securities laws, estimates of Inferred Mineral Resources may not form the basis of feasibility or prefeasibility studies, except in certain specific cases. Additionally, disclosure of “contained ounces” in a resource is permitted disclosure under Canadian securities laws, however the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measurements.

Accordingly, information contained in this Prospectus and the documents incorporated by reference herein containing descriptions of the Company’s mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of United States federal securities laws and the rules and regulations thereunder.

See “Glossary of Certain Technical Terms” in the Annual Information Form, which is incorporated by reference herein, for a description of certain of the mining terms used in this Prospectus and the documents incorporated by reference herein.

FINANCIAL INFORMATION

Unless otherwise indicated, all financial information included and incorporated by reference in this Prospectus is determined using IFRS, which differs from United States generally accepted accounting principles.

In this Prospectus, all dollar amounts referenced, unless otherwise indicated, are expressed in United States dollars and are referred to as”$” or “US$”. Canadian dollars are referred to as “C$”. The high, low and closing exchange rates for Canadian dollars in terms of the United States dollar for each of the indicated periods, as quoted by the Bank of Canada, were as follows

In addition, to the extent that any document or information incorporated by reference into this Prospectus is included in any report on Form 6-K, Form 40-F, Form 20-F, Form 10-K, Form 10-Q or Form 8-K (or any respective successor form) that is filed with or furnished by the Company to the SEC after the date of this Prospectus, that document or information shall be deemed to be incorporated by reference as an exhibit to the Registration Statement (as defined below) of which this Prospectus forms a part (in the case of Form 6-K and Form 8-K, if and to the extent set forth therein). The Company may also incorporate other information filed with or furnished to the SEC under the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), provided that information included in any report on Form 6-K or Form 8-K shall be so deemed to be incorporated by reference only if and to the extent expressly provided in such Form 6-K or Form 8-K.

Any statement contained in this Prospectus or in a document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded, for purposes of this Prospectus, to the extent that a statement contained herein or in any other subsequently filed document that also is, or is deemed to be, incorporated by reference herein modifies, replaces or supersedes such statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Prospectus; rather only such statement as modified or superseded shall be considered to constitute part of this Prospectus. The modifying or superseding statement need not state that it has modified or superseded a prior statement or include any other information set forth in the document that it modifies or supersedes. The making of a modifying or superseding statement shall not be deemed an admission for any purposes that the modified or superseded statement, when made, constituted a misrepresentation, an untrue statement of a material fact or an omission to state a material fact that is required to be stated or that is necessary to make a statement not misleading in light of the circumstances in which it was made.

A Prospectus Supplement containing the specific terms of an offering of Securities will be delivered to purchasers of such Securities together with this Prospectus to the extent required under applicable securities laws except in cases where an exemption from such delivery has been obtained and will be deemed to be incorporated by reference into this Prospectus as of the date of such Prospectus Supplement, but only for the purposes of the offering of Securities covered by that Prospectus Supplement.

The Company halted production at La Guitarra effective August 3, 2018 due to economic reasons and the mine is now under care and maintenance. The Company is reviewing strategic options for La Guitarra, including the potential sale of the operation, in order to reallocate capital and resources to projects which management believes have better economics and internal rates of return.

The Company also owns three advanced-stage silver exploration and development projects in México: the Plomosas Silver Project in Sinaloa State, the La Luz Silver Project in San Luis Potosi State and La Joya Silver Project in Durango State, as well as a number of exploration projects in México.

The Mineral Resources and Reserves reported in this Prospectus and the documents incorporated by reference herein represent the most up to date revisions completed for the Company’s operations and properties. Investors are cautioned against relying on such Mineral Resource and Reserve estimates since these estimates are based on certain assumptions regarding future events and performance such as: commodity prices, operating costs, taxes, metallurgical performance and commercial terms. Interpretations and Resource and Reserve estimates are based on limited sampling information that may not be representative of the mineral deposits.

Recent Developments

On January 29, 2018, the Company announced the closing of its offering of $150 million aggregate principal amount of 1.875% unsecured convertible senior notes due 2023 (the “Initial Notes”). The initial conversion rate for the Initial Notes is 104.3297 Common Shares per $1,000 principal amount of Initial Notes, equivalent to an initial conversion price of approximately $9.59 per Common Share.

On February 15, 2018, the Company announced the issuance of an additional $6.5 million aggregate principal amount of 1.875% unsecured convertible senior notes due 2023 (the “Over-Allotment Notes”) pursuant to the exercise in part of the over-allotment option granted to the initial purchasers of the Initial Notes. The Over-Allotment Notes have the same terms as the Initial Notes, including an initial conversion rate of 104.3297 Common Shares per $1,000 principal amount of Over-Allotment Notes, equivalent to an initial conversion price of approximately $9.59 per Common Share.

The Initial Notes and Over-Allotment Notes are governed by an indenture (the “Note Indenture”) entered into between the Company and Computershare Trust Company, N.A. on January 29, 2018. A copy of the Note Indenture is available under the Company’s profile on SEDAR at www.sedar.com.

On May 10, 2018 the Company announced the completion of its previously announced plan of arrangement with Primero (the “Arrangement”). The Company entered into an arrangement agreement with Primero on January 12, 2018 (the “Arrangement Agreement”) pursuant to which the Company agreed to acquire all of the issued and outstanding common shares of Primero (each, a “Primero Share”) in exchange for 0.03325 of a Common Share per Primero Share. The Company issued an aggregate of 6,418,594 Common Shares in exchange for all of the issued and outstanding Primero Shares. Primero is a mining company whose primary asset is the San Dimas Silver/Gold Mine. Upon closing of the Arrangement, Primero became a wholly-owned subsidiary of the Company and the former Primero shareholders became shareholders of the Company.

On May 10, 2018 and in connection with the Arrangement, the Company terminated the pre-existing silver purchase agreement (the “Prior San Dimas Stream Agreement”) with WPM and WPMI relating to production from the San Dimas Silver/Gold Mine and concurrently entered into a new precious metal purchase agreement (the “New San Dimas Stream Agreement”) with WPMI and FM Metal Trading (Barbados) Inc., a wholly-owned subsidiary of the Company. Pursuant to the New San Dimas Stream Agreement, WPMI is entitled to receive 25% of the gold production and 25% of the silver production converted to gold equivalent at a fixed exchange ratio of 70:1 at San Dimas in exchange for ongoing payments by WPMI equal to the lesser of (i) US$600 (subject to an annual inflation adjustment) and (ii) the prevailing market price, for each gold ounce delivered to an offtaker under the agreement. As part of the termination of the Prior San Dimas Stream Agreement, the Company issued to WPMI 20,914,590 Common Shares.

On May 10, 2018 the Company entered into an amended and restated credit agreement (the “Credit Agreement”) with the Bank of Nova Scotia, Bank of Montreal and Investec Bank PLC, each as lenders (the “Lenders”). Pursuant to the Credit Agreement, the Lenders agreed, among other things, to provide First Majestic with a US$75 million senior secured revolving term credit facility (the “New Credit Facility”). The Company had a previously existing credit agreement with Scotia Bank and Investec Bank PLC, as lenders, which was entered into on February 8, 2016 in connection with a senior secured credit facility, consisting of a US$25 million revolving credit line and a US$35 million term loan (the “Prior Credit Facility”). The New Credit Facility replaced the Prior Credit Facility and the prior credit facility of Primero.

Following completion of the Arrangement the Company arranged for the payment in full of Primero’s outstanding debentures in the aggregate principal amount of US$75 million. The debentures matured on May 11, 2018.

On July 16, 2018 the Company announced its intention to place La Guitarra under care and maintenance which became effective on August 3, 2018. The Company is reviewing strategic options, including the potential

13

sale of the operation, in order to reallocate capital and resources to projects with better economics and internal rates of return such as the newly acquired San Dimas operation

Note:

USE OF PROCEEDS

The use of proceeds from the sale of Securities will be described in the applicable Prospectus Supplement relating to a specific offering and sale of Securities. Unless otherwise specified in a Prospectus Supplement, among other potential uses, the Company may use the net proceeds for general working capital purposes, for expansion of existing operations, and for one or more other general corporate purposes including to complete corporate acquisitions, to, directly or indirectly, finance future growth opportunities and to repay existing or future indebtedness. More detailed information regarding the use of proceeds and the amount of net proceeds to be used for any such purposes will be set forth in any applicable Prospectus Supplement. The Company may invest net proceeds which it does not immediately use. Such investments may include short-term marketable investment grade securities. Management of the Company will retain broad discretion in allocating the net

14

proceeds of any offering of Securities under this Prospectus and the Company’s actual use of the net proceeds will vary depending on the availability and suitability of investment opportunities and its operating and capital needs from time to time. All expenses relating to an offering of Securities and any compensation paid to underwriting dealers or agents as the case may be, will be paid out of the proceeds from the sale of Securities, unless otherwise stated in the applicable Prospectus Supplement.

The Company may, from time to time, issue securities (including Securities) other than pursuant to this Prospectus.

PLAN OF DISTRIBUTION

The Company may, from time to time, during the 25-month period that this Prospectus remains valid, offer for sale and issue Securities. The Company may issue and sell Securities with an aggregate total offering price of up to US$300,000,000 (or the equivalent thereof in Canadian dollars or any other currencies).

The Company may sell the Securities, separately or together, to or through underwriters, dealers or agents, and also may sell Securities to one or more other purchasers directly or through agents. Each Prospectus Supplement will set forth the terms of the offering, including the name or names of any underwriters, dealers or agents and any fees or compensation payable to them in connection with the offering and sale of a particular series or issue of Securities, the public offering price or prices of the Securities and the proceeds to the Company from the sale of the Securities. Any initial offering price and discounts, concessions or commissions allowed or paid to dealers may be changed from time to time.

In addition, the Securities may be offered and issued in consideration for the acquisition of other businesses, assets or securities by the Company or one of its subsidiaries. The consideration for any such acquisition may consist of Securities separately, a combination of Securities or any combination of, among other things, Securities, cash and assumption of liabilities.

The Securities may be sold, from time to time in one or more transactions at a fixed price or prices which may be changed or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices, including in transactions that are deemed to be “at-the-market distributions” as defined in NI 44-102, including sales made directly on the TSX, NYSE or other existing trading markets for the Securities. The prices at which the Securities may be offered may vary as between purchasers and during the period of distribution of the applicable Securities. If, in connection with the offering of Securities at a fixed price or prices, the underwriters, dealers or agents have made a bona fide effort to sell all of the Securities at the initial offering price fixed in the applicable Prospectus Supplement, the public offering price may be decreased and thereafter further changed, from time to time, to an amount not greater than the initial offering price fixed in such Prospectus Supplement, in which case the compensation realized by the underwriters, dealers or agents will be decreased by the amount that the aggregate price paid by purchasers for the Securities is less than the gross proceeds paid by the underwriters, dealers or agents to the Company.

Underwriters, dealers and agents who participate in the distribution of the Securities may be entitled under agreements to be entered into with the Company to indemnification by the Company against certain liabilities, including liabilities under the U.S. Securities Act and Canadian securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. Such underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for, the Company in the ordinary course of business.

In connection with any offering of Securities, other than an “at-the-market distribution”, the underwriters, dealers or agents may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time. No underwriter, dealer or agent involved in an “at the market

15

distribution”, no affiliate of such an underwriter, dealer or agent and no person acting jointly or in concert with such an underwriter, dealer or agent will over-allot Securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities.

Unless otherwise specified in the applicable Prospectus Supplement, Subscription Receipts, Units and Warrants will not be listed on any securities exchange. Consequently, unless otherwise specified in the applicable Prospectus Supplement, there is no market through which the Subscription Receipts, Units and Warrants may be sold and purchasers may not be able to resell any such Securities purchased under this Prospectus. This may affect the pricing of the Subscription Receipts, Units and Warrants in the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation. No assurances can be given that a market for trading in Securities of any series or issue will develop or as to the liquidity of any such market, whether or not the Securities are listed on a securities exchange. See “Risk Factors”.

The Subscription Receipt Agreement will also specify that the Company may amend the Subscription Receipt Agreement and the Subscription Receipts, without the consent of the holders of the Subscription Receipts, to cure any ambiguity, to cure, correct or supplement any defective or inconsistent provision, or in any other manner that will not materially and adversely affect the interests of the holders of outstanding Subscription Receipts or as otherwise specified in the Subscription Receipt Agreement.

Units may be issued at various times comprising any combination of the other Securities described in this Prospectus. Each Unit will be issued so that the holder of such Unit is also the holder of each Security composing such Unit. Therefore, the holder of a Unit will have the rights and obligations of a holder of each included Security (except in some cases where the right to transfer an included Security of a Unit may not occur without the transfer of the other included Security comprising part of such Unit). The Units may be offered separately or together with other Securities, as the case may be.

The particular terms of each issue of Units will be described in the related Prospectus Supplement. This description may include, but is not limited to, any of the following, if applicable:

Warrants

The following description sets forth certain general terms and provisions of Warrants that may be issued hereunder and is not intended to be complete. The Warrants may be offered separately or together with other Securities, as the case may be. Warrants may be issued at various times under one or more warrant agreements or warrant indentures to be entered into by the Company and one or more banks or trust companies acting as warrant agent.

The statements made in this Prospectus relating to any warrant indenture and Warrants to be issued under this Prospectus are summaries of certain anticipated provisions thereof and do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the provisions of the applicable warrant indenture, if any. You should refer to the warrant indenture, if any, relating to the specific Warrants being offered for the complete terms of the Warrants. A copy of any warrant indenture, if any, relating to an offering or Warrants will be filed by the Company with the securities regulatory authorities in applicable Canadian offering jurisdictions and with the SEC after the Company has entered into it.

The particular terms of each issue of Warrants will be described in the related Prospectus Supplement. This description may include, but is not limited to, any of the following, if applicable:

The Initial Notes are convertible into Common Shares at an initial conversion rate of 104.3297 Common Shares per $1,000 principal amount of Initial Notes, equivalent to an initial conversion price of approximately $9.59 per Common Share.

23

On February 15, 2018, the Company announced the issuance of $6.5 million aggregate principal amount of 1.875% unsecured convertible senior notes due 2023 (the “Over-Allotment Notes”) pursuant to the exercise in part of the over-allotment option granted to the initial purchasers of the Initial Notes. The Over-Allotment Notes have the same terms as the Initial Notes, including an initial conversion rate of 104.3297 Common Shares per $1,000 principal amount of Over-Allotment Notes, equivalent to an initial conversion price of approximately $9.59 per Common Share.

The Initial Notes and Over-Allotment Notes are governed by the Note Indenture entered into between the Company and Computershare Trust Company, N.A. on January 29, 2018. A copy of the Note Indenture is available under the Company’s profile on SEDAR at www.sedar.com.

24

The Common Shares are listed on the NYSE in the United States under the symbol “AG”. On November 2, 2018, being the last trading day prior to the date of this Prospectus, the closing price of the Common Shares on the NYSE was US$5.92. The price range and trading volume of the Common Shares for each month from October 2017 to November 2, 2018, as reported by the NYSE, are set out below:

MARKET FOR SECURITIES

The Common Shares are listed and posted for trading on the TSX in Canada under the symbol “FR” and are listed on the NYSE in the United States under the symbol “AG”. Trading price and volume of the Common Shares will be provided as required in each Prospectus Supplement to this Prospectus.

RISK FACTORS

Before deciding to invest in any Securities, prospective purchasers of the Securities should consider carefully the risk factors and the other information contained in and incorporated by reference into this Prospectus and any applicable Prospectus Supplement relating to a specific offering of Securities before purchasing the Securities. An investment in the Securities offered hereunder is speculative and involves a high degree of risk. Information regarding the risks affecting the Company and its business is provided in the documents incorporated by reference in this Prospectus, including in the Company’s most recent annual information form under the heading “Description of Business - Risk Factors”. Additional risks and uncertainties not known to the Company or that management currently deems immaterial may also impair the Company’s business, financial condition, results of operations or prospects. See “Documents Incorporated by Reference”.

No Assurance of Active or Liquid Market

No assurance can be given that an active or liquid trading market for the Common Shares will be sustained. If an active or liquid market for the Common Shares fails to be sustained, the prices at which such shares trade may be adversely affected. Whether or not the Common Shares will trade at lower prices depends on many factors, including the liquidity of the Common Shares, prevailing interest rates and the markets for similar securities, general economic conditions and the Company’s financial condition, historic financial performance and future prospects.

There is no public market for the Warrants, Subscription Receipts or Units and, unless otherwise specified in the applicable Prospectus Supplement, the Company does not intend to apply for listing of such Securities on any securities exchange. If the Warrants, Subscription Receipts or Units are traded after their initial issue, they may trade at a discount from their initial offering prices depending on the market for similar securities and other

25

factors including general economic conditions and the Company’s financial condition. There can be no assurance as to the liquidity of the trading market for the Warrants, Subscription Receipts or Units or that a trading market for these securities will develop.

Public Markets and Share Prices

The market price of the Common Shares and any other Securities offered hereunder that become listed and posted for trading on the TSX, NYSE or any other stock exchange could be subject to significant fluctuations in response to variations in the Company’s financial results or other factors. In addition, fluctuations in the stock market may adversely affect the market price of the Common Shares and any other Securities offered hereunder that become listed and posted for trading on a stock exchange regardless of the financial performance of the Company. Securities markets have also experienced significant price and volume fluctuations from time to time. In some instances, these fluctuations have been unrelated or disproportionate to the financial performance of issuers. Market fluctuations may adversely impact the market price of the Common Shares and any other Securities offered hereunder that become listed and posted for trading on a stock exchange. There can be no assurance of the price at which the Common Shares or any other Securities offered hereunder that become listed and posted for trading on a stock exchange will trade.

Additional Issuances and Dilution

The Company may issue and sell additional securities of the Company to finance its operations or future acquisitions. The Company cannot predict the size of future issuances of securities of the Company or the effect, if any, that future issuances and sales of securities will have on the market price of any Securities issued and outstanding from time to time. Sales or issuances of substantial amounts of securities of the Company, or the perception that such sales could occur, may adversely affect prevailing market prices for Securities issued and outstanding from time to time. With any additional sale or issuance of securities of the Company, holders will suffer dilution with respect to voting power and may experience dilution in the Company’s earnings per share. Moreover, this Prospectus may create a perceived risk of dilution resulting in downward pressure on the price of the Company’s issued and outstanding Common Shares, which could contribute to progressive declines in the prices of such securities.

The Company has Broad Discretion in the Use of the Net Proceeds from this Offering

Management of the Company will have broad discretion with respect to the application of net proceeds received by the Company from the sale of Securities under this Prospectus or a future Prospectus Supplement and may spend such proceeds in ways that do not improve the Company’s results of operations or enhance the value of the Common Shares or its other securities issued and outstanding from time to time. Any failure by management to apply these funds effectively could result in financial losses that could have a material adverse effect on the Company’s business or cause the price of the securities of the Company issued and outstanding from time to time to decline.

Geo., then as an independent consultant to the Company, J. Morton Shannon, P. Geo., of AMC Mining Consultants (Canada) Ltd., Rodney Webster, M.AIG of AMC Consultants Pty Ltd., Gabriel Voicu, P.Geo., then of Primero, and Maria E. Vazquez Jaimes, P. Geo., Jesus M. Velador Beltran, MMSA QP, and Ramon Mendoza Reyes, P. Eng. Dave Laudrum, P. Geo., and Patrick McCann, P. Eng., then of Primero, prepared certain scientific or technical information contained in the Primero Annual Information Form. Mr. Ramon Mendoza Reyes, P. Eng., has approved the scientific and technical disclosure contained in this Prospectus and the documents incorporated by reference herein. Each of Ms. Vazquez Jaimes, Mr. Velador Beltran, Mr. Mendoza Reyes, Mr. Spurgeon and Mr. Kulla are employees of the Company. Each of Ms. Vazquez Jaimes, Mr. Velador Beltran, Mr. Mendoza Reyes, Mr. Spurgeon and Mr. Kulla hold Common Shares and/or stock options of the Company which represent less than 1% of the outstanding shares of the Company. To management’s knowledge, no other such person has any registered or beneficial interest, direct or indirect, in any securities or other property of the Company (or of any of its associates or affiliates).

LEGAL MATTERS

Certain legal matters in connection with the offering will be passed upon on behalf of the Company by Bennett Jones LLP, Vancouver, B.C., as to Canadian legal matters, and Dorsey & Whitney LLP, Vancouver, B.C. and Seattle, Washington, as to United States legal matters. As of the date hereof, the partners and associates of Bennett Jones LLP own, directly or indirectly, less than 1% of the Common Shares and the partners and associates of Dorsey & Whitney LLP own, directly or indirectly, less than 1% of the Common Shares. In addition, certain legal matters in connection with any offering of Securities will be passed upon for any underwriters, dealers or agents by counsel to be designated at the time of the offering by such underwriters, dealers or agents, as the case may be.

Keith Neumeyer, a director of the Company, resides outside of Canada. Mr. Neumeyer has appointed the following agent for service of process in Canada:

Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person that resides outside of Canada, even if the person has appointed an agent for service of process.

ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

The Company is governed by the laws of British Columbia and its principal place of business is outside the United States. The majority of the directors and officers of the Company and the experts named under “Interests of Experts” herein are resident outside of the United States and a substantial portion of the Company’s assets and the assets of such persons are located outside of the United States. Consequently, it may be difficult for United States investors to effect service of process within the United States on the Company, its directors or officers or such experts, or to realize in the United States on judgments of courts of the United States predicated on civil liabilities under the U.S. Securities Act. Investors should not assume that Canadian courts would enforce judgments of United States courts obtained in actions against the Company or such persons predicated on the civil liability provisions of the United States federal securities laws or the securities or “blue sky” laws of any state within the United States or would enforce, in original actions, liabilities against the Company or such

27

persons predicated on the United States federal securities or any such state securities or “blue sky” laws. A final judgment for a liquidated sum in favour of a private litigant granted by a United States court and predicated solely upon civil liability under United States federal securities laws would, subject to certain exceptions identified in the law of individual provinces of Canada, likely be enforceable in Canada if the United States court in which the judgment was obtained had a basis for jurisdiction in the matter that would be recognized by the domestic Canadian court for the same purposes. There is a significant risk that a given Canadian court may not have jurisdiction or may decline jurisdiction over a claim based solely upon United States federal securities law on application of the conflict of laws principles of the province in Canada in which the claim is brought.

The Company filed with the SEC, concurrently with the Registration Statement, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Company appointed Puglisi & Associates, with an address at 850 Library Avenue, Suite 204, Newark, Delaware 19711, as its agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against or involving the Company in a United States court arising out of or related to or concerning the offering of Securities under the Registration Statement.

CONTRACTUAL RIGHTS OF RESCISSION

Original purchasers of Securities which are convertible, exchangeable or exercisable for other securities of the Company, including Subscription Receipts and Warrants if offered separately without any other Securities, will have a contractual right of rescission against the Company in respect of the conversion, exchange or exercise of such Securities. The contractual right of rescission will entitle such original purchasers to receive the amount paid upon conversion, exchange or exercise, upon surrender of the underlying securities gained thereby, in the event that this Prospectus, the relevant Prospectus Supplement or an amendment thereto contains a misrepresentation, provided that: (i) the conversion, exchange or exercise takes place within 180 days of the date of the purchase of such Securities under this Prospectus and the applicable Prospectus Supplement; and (ii) the right of rescission is exercised within 180 days of the date of the purchase of such Securities under this Prospectus and the applicable Prospectus Supplement. This contractual right of rescission will be consistent with the statutory right of rescission described under section 131 of the Securities Act (British Columbia), and is in addition to any other right or remedy available to original purchasers under section 131 of the Securities Act (British Columbia) or otherwise at law.
